Piezoelectric materials are materials which generate electricity when mechanically strained, and deform under an electric field. Due to their distinguished electromechanical coupling effect, piezoelectric materials have widely been used in many applications, such as acoustic emission microsensors, vibration monitors, molecular recognition biosensors, precision positioners, micropumps, and linear stepper motors, energy harvesting devices, and so on. Reliability of functional devices heavily depends on the proper functioning of piezoelectric, smart components.

压电材料是一种在机械张力作用下产生电能并在电场作用下变形的材料。压电材料由于其独特的机电耦合效应，在声发射微传感器、振动监测仪、分子识别生物传感器、精密定位器、微泵、线性步进电机、能量收集装置等领域得到了广泛的应用。功能器件的可靠性在很大程度上取决于压电智能元件的正常运行。
